HINGED FUNNEL.

Specification of Letters Patent. Patented J ul y 8, 1919.

, Application filed January 3, 1917. Serial No. 140,378.

To all whom it may concern:

Be it known that I, JOHN W. ANDERSON, a citizen of the United States, and a resident of New London, in the county of New London and State of Connecticut, have invented certain new and useful Improvements in Hinged Funnels; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to submarine boats. Such a vessel, when fitted with steam power for surface propulsion must" be provided with some form of funnel for the escape of surplus steam and the gases of combustion, and yet when the boat is submerged all openings must be closed tight and all external parts of the funnel must be stowed away in order to reduce the boats resistanceto submerged propulsion. T y

In some cases telescopic funnels have been suggested; but to these there are serious practical objections. In the first place the height of the funnel should not be such as to prevent a substantially complete telescoping of the funnel down into the superstructure, and yet the funnel must be high enough for satisfactory service in carrying off the surplus steam and the products of combustion. The telescoping Organization, moreover, even if a unitary funnel is used, necessitates unsatisfactory complications of parts, joints, &o.

In other cases the attempt has been made to pass the gases up through passages built permanently into the superstructure;- but the disadvantages of such an arrangement are too obvious to need discussion.

The present invention involves the provision of a unitary stack or funnel hinged to the bull in the lower part of the superstructure space adjacent to the upper mouth of the boiler uptake and movable to and from a substantially vertical position in continuation of the uptake, a hinged door adapted to be swung to open the intake as the stack is moved to its vertical position and to close the intake as the stack is moved away from its vertical position, and means for thus operating the'stack and the door controlled from within the boat. The stack is of greater length than the height of the superstructure space, and accordingly an elon gated opening is provided in the superstructure deck so that the stack may be swung away from its vertical position and through the opening for stowage below the deck.

One of the Objects of the invention is to provide a reliable, rugged and conveniently actuable means which may be employed for Operating the stack from the interior of the vessel, which means is self-locking in all positions of the stack.

Another object is to provide, as a movable part of the escape steam line of the boiler, an auxiliary stack, funnel or escape pipe preferably similarly mounted and similarly controlled. have the fixed part of the steam line from the boiler terminate adjacent to the uptake, to mount the auxiliary steam pipe on the hinged stack in position to form a continuationof the fixed steam pipe when the stack forms a continuation of the uptake, and to arrange the door so that it closes the fixed steam pipe when it closes the uptake.

In the accompanying drawing, illustrat To this end it is preferred to.

ing the preferredembodiment of the inven- I tion,

Figure 1 is a vertical sectional view showing the stack horizontal and, the door in closed position;

Fig. 2 is a view similar to Fig. 1, showing the stack vertical and the door in open position; and

Fig. 3 is a sectional View taken on the line 3-3 of Fig. 2.

4 indicates the hull of the boat. A permanently built-in open-topped steam pipe 5 leads from a safety valve 6 carried by the boiler 7 This pipe 5 extends above the hull roof, as does a permanently built-in Opentopped passage or uptake 8 leading from the combustion chamber (not shown) of the boiler.

A stack 9, for forming a continuation of the uptake 8 as shown in Fig. 2, is mounted on a hinged plate. 10 fixed on a pintle or shaft 11, so that when the shaft is rotated in a counter-clockwise direction the stack may be swung downward through an Opening 12 formed in a superstructure deck 13 and thus be uncoupled from uptake 8 and stowed in superstructure space 1 1.

The stack 9 and the auxiliary steam pipe 15 move as one unit, either to lie as shown in Fig. 1, when the stack and pipe form continuations of the uptake 8 and the pipe 5, or as shown in Fig. 2, when such parts are uncoupled. The pipe 15 is anchored adjacent to its lower end in a web 10 which is a part of the hinge plate 10 (Fig. 3) and is anchored adjacent to its upper end by means of a bracket 16. Opening 12 may or may not have associated therewith an adjustable cover, but if such a cover is provided it need only be adapted for making a spraytight closure.

Ordinarily for cruising in light seas and when the stack and the auxiliary pipe are disconnected, the portions of pipe 5 and uptake 8 which project above the hull-roof act as protective coamings; but preparatory to submergence it is necessary to close the pipe 5 and the uptake 8 in a watertight manner. In the present instance, a single door 17 forms a part of a hinge-plate 18 secured to a pintle or shaft 19. A single door for the purpose specified is very desirable, and this is made possible by bringing together in one place on the roof of the hull all openings which serve the boiler plant. This door 17 (Figs. 2 and 3) is provided on its underside with a well 17 for closing pipe 5 in a. watertight manner, and with a well 17 for similarly closing uptake 8 when shaft 19 is rotated in a counter-clockwise direction to lie as disclosed in Fig. 1.

According to the present construction, when the stack 9 and door 17 are being changed from the locations of Fig. 1 to those of Fig. 2, or vice versa, the stack swings through an angle of 90 and the door through an angle twice as large. Parts of the door and stack, moreover, have intersect-ing arcs of movement as indicated by broken line arrows in Fig. 1. The swinging movements of the door and stack should, however, be so correlated that the door closes the uptake as soon as possible after the stack commences to leave its vertical position, and yet so that in moving the stack to its vertical position the stack takes up such position just as the door takes up the location of Fig. 2. The mechanism controlling all these operations, in order to be self-locking, should have its various elements positively interconnected and positively actuated. These ends are attained as follows:

The movements of the door 17 are controlled by the rotations of beveled gear 20 fixed on a sleeve 21 (Fig. 1) journaled in bearings 22, the sleeve having secured to its opposite end a spiral gear 23 which meshes with a spiral gear 2% fixed on pintle or from the location of F ig.

shaft 19. The movements of stack 9 are controlled by the rotations of beveled gear 25 fixed on a shaft 26 loosely extending through sleeve 21, the shaft 26 having secured to its opposite end a spiral gear 27 which meshes with a spiral gear 28 fixed on pintle or shaft 11. These beveled gears 20 and 25 are both actuated by a mutilated. bevel gear 29 with which they are adapted to mesh; the gear 29 being fast on the up- "per end of a vertical shaft 30 on the lower end of which is fixed a worm gear 31 cooperating with a worm 32 on the same shaft with and driven by a hand-wheel 33 located within the hull.

With the parts arranged as shown in Figs. 2 and 3, to redispose them as disclosed in Fig. 1 hand-wheel 33 is turned in the direction of the arrow a marked thereon, to cause all the gears above mentioned to turn in the directions of their arrows a. As a result the mutilated gear 29 first causes the stack 9 to swing downward as shown in Fig. 1, at the same time moving the door 2 to a position intermediate its open and closed positions. As soon as the stack becomes disposed as shown in Fig. 1, the portion 29 of the gear 29 comes opposite the gear 25, and the latter gear then becomes idle, so that further rotation rotation merely of the gear 20 to move the door to close the uptake. Just as this last movement is completed, the gear 29 again meshes with gear 25, while remaining in mesh with gear 20, the mutilated portion 29 of gear 29 now being in the location 29"; and so the stack and door are positively locked in the positions of Fig. l.

lVith the parts arranged as shownin Fig. 1, to redispose them as'disclosed in Figs. 2 and 3 the hand-wheel 33 is turned in the opposite direction to that of the arrow a marked thereon, all the other gears then turning in directions opposite to their arrows a. The mutilated portion 29 of the gear 29 being at the location 29", the first part of the rotation of gear 29 rotates merely the gear 20, leaving the gear 25 temporarily idle. As a result, the door is swung sufliciently away from the uptake to permit the stack to be swung up toward its vertical position. This accomplished, the gear 29 again comes into mesh with the gear 25, and, remaining in mesh with the gear 20, completes the readjustment of stack and door by simultaneously moving them to take up the locations of Figs. 2 and 3.
